Improvement in lanterns



HIRAM WENTWORTH AND V. B.

CLARK, OF BIPON, WISCONSIN.

IM PROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 73,481, dated January21, 1868.

To all whom it may concern Be it known that we, HIRAM WnN'rwoR'rH and V.B. CLARK, of Ripon, in t-he county of Fond du Lac, in the State ofWisconsin, have invented a new and Improved Mode of Securing andFastening and Unfastening the Oil-Pot in Lanterns; and we do herebydeclare that the followin g is a full and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

The nature of our invention consists in providing a lantern-bottom,marked A in the drawings, with outlines showing the positions of theoilpot, spring, and bracket in the same; also, showing, in perspective,a projecting iiange, marked J, at the bottom of the lan tern, with thepoints of pressure on the spring F, marked L and K, above and below theiiange J, and the guard, marked E, attached to the outside of thelantern-bottom, protecting the spring.

rIhe second perspective View represents an oil-pot, marked B, showingthe position of the ange, marked C also, the projection, marked D, atthe top ot' the oil-pot, which rests when in place upon the end of thesprin g F, at H, and the elbow of the bracket Gr at the point marked M.rIhis projection D is an extension only of the top of the oil-pot B.

The third view of the spring, marked F, shows the arrangement of a hook,H, formed at the upper end of the spring; also, in the fourthperspective view, is shown the bracket, marked G, with the point orelbow, marked M.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation. We constructour lantern-bottom in any of the known forms, of tin, brass, copper, oroi' any other suitable metal or material.

The ange C is constructed by soldering a narrow strip, of the samematerial of which the oil-pot is made, near the bottom of the oilpot, insuch a manner that the upper side of the flange will, when in use, restagainst the bottom of the flan ge J on the lantern-bottom, therebyholding the oil-pot rmly in its place. The bracket G is also made of thesame material, the two ends soldered fast to the lantern-bottom, so thatthe elbow or point M will project inward, and the lower end willgradually slant outward, and form a guide to the oil-pot, to the pointM. The spring F may be constructed of brass or any other metal, withsufficient spring and strength to force the oil-pot B to its properplace. The guard E is made of the same material as the rest of thelantern-liottom and soldered over and near the lower end of the spring Fon the side of the lantern-bottom.

To remove the oil-pot B from the lanternbottom, press the spring F at Lor K. To adjust it for use, press it into the opening in thelantern-bottom.

We claim as our invention- 1. The spring F, as applied tolantern-bottoms.

2. The bracket G and manner oi' attaching it opposite to the spring F.

3. The arrangement of the spring F, so as to be operated both above andbelow the lian ge J, at L and K.

4. The guard E.

5. The iiange C on oilpot B. 4

6. The projection D at the top of the oilpot B.

7. The arrangement of the different parts, substantially as described,and for the purposes specified.
